4iiii PRECISION Power Meter For Shimano XTR M9000

The 4iiii PRECISION Power Meter for Shimano XTR M9000 is the lightest, most affordable direct force power meter available. The added weight of the 4iiii PRECISION is only 9 grams and it is accurate to within +/- 1.0%.

The 4iiii PRECISION is a left-only crank arm-based power meter and replaces your current left side crank arm. The 4iiii takes the power that is generated by your left leg and doubles it in order to determine your total power output.

In addition to being affordable, lightweight and highly accurate, the 4iiii PRECISION measures precise cadence data, has 3D power meter technology capable of measuring tri-axial strain and is compatible with both ANT+ and Bluetooth SMART devices.

Easy to Install

Installation is a breeze. Just swap it out for your current left-side crank arm and you’re ready to ride! Installation takes minutes…not hours.

ANT+ & Bluetooth SMART
